You will need our consent under the Planning (Listed Building and Conservation Areas) Act 1990, to demolish a listed building or for any alteration or extension which would affect its character as a building of architectural or historic interest.
The need for listed building consent is different from planning permission but the process is very similar.
It is a criminal offence to carry out works to a listed building without prior listed building consent - even if you did not know that the building was listed.
Carrying out unauthorised work is punishable by a fine or a prison sentence and we can require you to put the building back the way it was.
